Bernard Tomic has moved through to the second round of the Abierto Mexicano Telcel in Acapulco with a straight-sets victory over Rajeem Ram.

The No.5 seed beat the American 7-5 6-3 in one hour and 20 minutes, flipping the script after losing to Ram in the opening round of last week’s Delray Beach Open.

Tomic goes on to face Frenchman Adrian Mannarino, who beat Mexico’s Tigre Hank for the loss of just three games.

Meanwhile, another Queenslander, John Millman, found the going tougher at the ATP 500-level hardcourt tournament.

Drawn to play top seed David Ferrer, Millman battled but eventually fell to a 6-4 6-2 defeat.

Earlier on Tuesday, Sam Groth’s miserable year continued, with the Australian losing in three sets to Russian Dmitry Tursunov.

World No.75 Groth went down 6-4 3-6 7-5 on Tuesday to record his fifth first-round loss of 2016.

Since losing to Andy Murray in the second round of the Australian Open, the Victorian this month was eliminated in the first round of the Challenger Tour’s Dallas Championships and three ATP tournaments – the Memphis Open, Delray Beach Open and now in Acapulco.
